Where does “nondisabled” come from?

I can't write this etymology because the chain provided doesn't support "nondisabled." The chain traces "disable" back through Latin and Proto-Indo-European, but "nondisabled" is a modern English formation using the prefix "non-" added to "disabled"—a prefix not present in the etymological chain given. To write an accurate one-sentence origin, I would need either: 1. A chain that actually traces "nondisabled," or 2. Clarification that you want the etymology of "disabled" instead Could you verify the headword or provide the correct chain?
